DIGITAL SHIFT REGISTER

摘要

A digital shift register comprising a series connection of a number of source-followers, the input of each source-follower being connected both to a storage capacitance and to an electronic switch for establishing the reference level at the relevant capacitance. Between the inputs of at least some of the source-followers and the associated clock lines variable capacitances are included. The variable capacitances serve to compensate for the voltage losses occurring the source-followers as a result of the threshold voltages of the transistors employed in said source-followers.
